FREDERICK W. NOLTE, OF VICTORIA, BRITISH COLUMBIA, CANADA.

EYEGLASS-MOUNTING.

To all whom it may concern Be it known that I, FREDERICK \V. NOLTE, of the city of Victoria, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Eyeglass-Mountings, of which the following is a specification.

This invention relates to eye-glass mountings in which nose guard levers are employed movable by the fingers to spread the nose guards and yieldingly pressed toward their normal position by spring means and my object is to devise a construction which will enable me to dispense with separate springs and in which the bridge ends are readily formed by deforming the normal cross section of the bridge wire.

I attain my object by means of a construction in which each nose guard lever is bent upon itself to form parts adapted to resiliently resist pressure tending to separate them or to press them closer together. This lever is so engaged with the bridge end that any rocking movement of the lever tends to either spread or compress the parts of the lever substantiallv as hereinafter more particularly described and then definitely claimed.

Figure 1 is a plan view of a part of a pair of eve-glasses showing my improved mounting. Fig. 2 is a plan view from the under side of the same mounting. Fig. 3 is a cross section of the same. Fig. 4 is a cross section of a modification. Fig. 5 is a similar view of another modification. Fig. 6 is a rear view of the same mounting, partly in section. Fig. 7 is a similar view of another modification. Fig. 8 is a cross section of the same modification. Fig. 9 is a plan view of another modification. Fig. 10 is a rear elevation of the same mounting partly in section. Fig. 11 is a cross section of the same mounting. Fig. 12 is a front elevation partly in section of another modification. Fig. 13 is a front elevation of another modification. Fig. 14 is a plan view of the same modification. Fig. 15 is a front elevation partly in section of yet another modification.

In the drawings like numerals of refer ence indicate corresponding parts in the different figures.

Referring particularly to Fig. 1, 1 is the bridge, 2 the bridge end, 3 the lens clamp Specification of Letters Patent.

and 4 the lens. In cross section the bridge end, as shown particularly in Fig. 3, is con vex at one side, preferably the upper side.

While almost any form in which the center lies above the edges, the surface in between rising by a gradient, would be suitable for the purposes of my invention, yet I find a semi-circular or semi-elliptical form, such as shown, the best.

The nose guard lever 5 has any suitable nose guard 6 formed thereon. The nose guard lever is doubled on itself to embrace the bridge end. One of the embracing parts is fitted to the shape of the convex surface of the bridge end. In Figs. 1, 2 and 3 I show the main part of the lever as so fitted, the other parts 7 lying against the flat under side of the bridge end.

The finger grip 8 in the nose guard lever forms a forwardly extending finger grip. This finger grip may be either single, as shown in Fig. 1, or may be formed with several coils, as shown in Figs. 4 and 5.

The finger grip 8 it will be noted is bent laterally toward the lens so that the part 7 of the nose guard lever crosses the same. It is also cut away at its rearward edge and bent up to form the finger 9 .which lies beside the rearwardly extending upper part of the lever and serves to keep the upper and lower parts of the lever in alinement.

It will be readily understood on inspection of the drawings that if the nose guard lever be rocked from the normal position shown in Figs. 1, 2 and 3 that the parts of the nose guard lever will be sprung apart and so placed under tension, their natural spring tending at all times to cause them to assume the position shown.

The modification shown in Fig. 4 is in all respects similar to that shown in Figs. 1, 2 and 3, with the exception that the finger grip 8 is formed of several coils instead of being a double bend.

In Figs. 5 and 6 I show a modification in which the doubled over part 7 is fitted to the convex surface of the bridge end 2 and in which the bridge end is formed with a part 10 lying under the nose guard lever and holding the latter in close contact with the under side of the bridge end.

In Figs. 7 and 8 the arrangement shown in Figs. 5 and 6 is reversed, the under side of the bridge end 2 being convex and the part '7' of the lever also lying underneath the bridge end and fitted to the shape of the same.

In Figs. 9, 10 and 11 I show a modification in which the bridge end is bent in the direction of its length, forming an upper concave and a lower convex surface. The parts of the nose guard lever cross the bridge end and one of them, preferably the upper in cross section, exactly fits the concave upper surface of the bridge end. A heavy pin 11 is rigidly secured tothe lower part of the nose guard lever and extends up through the bridge end and the upper part. Suificient space is allowed between the head and the upper part of the lever to permit of the rise and fall of the latter when the nose guard lever is sprung from its normal position.

In Fig. 12 I show a modification in which the configuration of the bridge end is the same as in Figs. 9, 10 and 11, but both ends of the nose guard lever 5 lie above the bridge end. The pin 12 passes through both parts of the nose guard lever and is screwed into the bridge end. In this form the nose guard lever is turned from its normal position; the tendency is to press the two parts of the nose guard lever toward one another and not to spring them apart as in the prior constructions shown and described.

In Figs. 13 and 1 1 the bridge end is shaped in the manner shown in Figs. 9, 10 and 11, but the pin 12 is omitted and the parts are held in place by a part 13 formed by bending over the bridge end to embrace the parts of the nose guard lever as shown.

In Fig. 15 I show an arrangement which combines the features and modifications shown in Fig. 12 and Figs. 18 and 14 as the part 13 and the pin 12 are both employed.

It will be seen that all the forms described operate in substantially the same manner; that is, that the nose guard lever is for-med of two parts which tend to maintain a certain normal position, but which may be sprung apart or toward one another by engagement with a surface, the bridge end engaging a similarly shaped surface on one of the parts of the nose guard lever, the sur faces being so shaped that any turning of the nose guard lever from the normal position produces the displacement of the parts of the nose guard lever described.

hat I claim as my invention is 1. In an eye-glass mounting the combination with a bridge end, of a nose guard lever doubled on itself to form two parts and mounted to rock on the bridge end, said lever and bridge end having correlated engaging surfaces adapted to spring said parts of the lever when the latter is rocked.

2. In an eye-glass mounting the combination with a bridge end, of a nose guard lever doubled 011 itself to form two parts and mounted to rock on the bridge end, said'lever and bridge end having engaging surfaces convex and concave in section relative to one another in one plane and in substantial parallelism in a plane substantially at right angles to the first.

3. In an eye-glass mounting the combination of a bridge end, of a nose guard lever doubled on itself to embrace the bridge end, said lever and bridge end having correlated engaging surfaces adapted to spring said parts of the lever when the latter is rocked.

1. In an eye-glass mounting the combination with a bridge end, of a nose guard lever doubled on itself to embrace the bridge end, said lever and bridge end having engaging surfaces convex and concave in section relative to one another in one plane and in substantial parallelism in a plane substantially at right angles to the first.

5. In an eyeglass mounting the combination with a bridge end having one surface convex in a cross section taken transversely to the length of the bridge, of a nose guard lever doubled on itself to embrace said bridge end and fit said convex surface.
